How to Make AI Videos on Your Own: A 5-Step Workflow

One person can make a complete AI video by following five steps: a scene-by-scene script, reference frames, clip generation, scene assembly with a voice-over, and an AI disclosure when you publish.

Step 1: split your script into scenes of 4 to 10 seconds

As of October 2026, each clip made with Gemini Omni Flash in Google Flow runs 4, 6, 8, or 10 seconds, according to Flow's models and features page. That means a 30-second video needs about 3 to 8 clips joined together.

So do not open the tool before you have a script. Write each scene on its own line: who does what, where, what the light looks like, and the dialogue if there is any. Each line later becomes a prompt. For any scene with facts (prices, figures, dates), put the source link next to it so you can check it in the last step.

Step 2: build reference frames so characters look the same in every scene

The most visible flaw in AI video is a character or product that changes its face between scenes. The Flow page on creating videos suggests using ingredients: the same character image and product image added to every prompt.

Flow supports three ways to keep things consistent:

Drag a reference image into the prompt box, then describe how to use it in the scene.
Type @ followed by the name of a character you created to bring it back, or type @me to use your own avatar.
Set a first frame and a last frame, so the AI creates the motion between the two images.

Google recommends shooting product or subject references on a plain or segmented background for the best results. You can create the frame images right inside Flow with the Nano Banana image models.

Step 3: make AI video clips in Google Flow, drafting at 360p first

The Get started with Flow page lists three conditions: you are 18 or older, you are in a supported region, and you have a Google AI Plus, Pro, or Ultra plan. Check that your country and language appear on the list of places where Flow is available. Google recommends English prompts for the best results, because output quality in other languages may vary.

The Flow credits page says something different. With or without a plan, every account gets 50 credits a day, and unused daily credits do not roll over. People without a plan can still generate images and use the Flow Agent, but during peak hours, roughly 2 PM to 5 PM UTC, they may not be able to generate videos. The two pages did not fully match as of Oct 11, 2026, so sign in with your own account and see what you get.

Google AI Plus adds 200 credits a month, and Google AI Pro adds 1,000. The Get started page also says every output made with Veo, Omni, or Nano Banana in Flow carries an invisible SynthID watermark. A visible watermark can be switched on or off from the menu under your profile picture, but it is applied automatically for users in India, South Korea, and Vietnam who are not on the Google One AI Ultra 20x plan (read Oct 19, 2026).

Every generation costs credits, so make cheap drafts first. Gemini Omni Flash creates 360p video at half the credit cost of 720p. Pro and Ultra subscribers can upscale a 360p clip to 720p for 0 credits.

A lean routine for one person: make 2 to 3 variations at 360p for each scene, pick the one that works, then upscale it to 720p. Before you click generate, Google also reminds you to check the active model, resolution, and latest credit cost in the prompt box settings.

Step 4: assemble scenes with Scenebuilder and lengthen them with Extend

Once you have enough clips, you can join them inside Flow. The page on editing videos and building scenes says Scenebuilder arranges several clips in a sequence, reorders them, trims the start and end of each clip, previews the whole sequence, and downloads the scene.

If a scene is too short, the Extend button adds a new section to the end of the clip based on your description. Note that as of Oct 9, 2026, Flow can only extend videos generated with Veo. When you edit a clip, the original is not lost: the History panel keeps every version along with the prompt you used.

Step 5: add a voice-over and captions, then check everything by eye

Flow has a voice library. Under your text prompt, click Add, then Voices, hover over a voice to hear a 10-second sample, then type @Voice in your prompt to keep the same voice across several clips. Google notes that voice references work only with generations that use ingredients, and some voice features are available only in certain regions, so check what your account shows.

Automatic captions save time but are not fully reliable. YouTube's automatic captions page states that machine captions can be wrong because of mispronunciation, accents, dialects, or background noise. YouTube advises you to always review them and fix any mistakes. Names and numbers are the places to check hardest.

Do you have to disclose AI-generated videos on YouTube?

Yes, if the video looks real. YouTube's page on disclosing GenAI content requires disclosure when AI makes a real person appear to say or do something they did not, or alters footage of a real event or place. The other two cases are a realistic scene that never happened and music that is the main focus of the video.

When you upload, go to the Attributes section and set "AI use" to Yes. YouTube says disclosure does not limit a video's reach or affect your ability to earn money. On the other hand, creators who consistently fail to disclose may get a label applied manually, have content removed, or be suspended from the YouTube Partner Program.

Four common mistakes when you make AI videos alone

Writing long prompts in a language other than English. Flow recommends English. Keep the dialogue in your script in your own language, and write short scene descriptions in English.

Using photos of famous people as references. Flow does not support generating videos of prominent people in any region. It also does not allow editing uploaded videos of identifiable minors.

Generating every scene straight at 720p. You run out of credits before you have all your scenes. Draft at 360p, lock the scene, then upscale.

Publishing without checking the facts. Any line of dialogue with numbers needs to be matched against the source you noted in Step 1.
